The present disclosure provides a method that includes providing a semiconductor substrate having a first region and a second region; forming a first gate within the first region and a second gate within the second region on the semiconductor substrate; forming first source/drain features of a first semiconductor material with an n-type dopant in the semiconductor substrate within the first region; forming second source/drain features of a second semiconductor material with a p-type dopant in the semiconductor substrate within the second region. The second semiconductor material is different from the first semiconductor material in composition. The method further includes forming first silicide features to the first source/drain features and second silicide features to the second source/drain features; and performing an ion implantation process of a species to both the first and second regions, thereby introducing the species to first silicide features and the second source/drain features.

A near eye display device includes a display and a first waveguide element, the first waveguide element including a light incoming surface, a light exiting surface, a reflective inclined surface and beam splitting elements. An image beam provided by the display enters the first waveguide element via the light incoming surface and is reflected by the reflective inclined surface in the first waveguide element to the beam splitting elements, and is split by the beam splitting elements and leaves the first waveguide element via the light exiting surface. The reflective inclined surface has a first reflectivity distribution in a first incident angle range and a second reflectivity distribution in a second incident angle range. An angle in the second incident angle range is greater than an angle in the first incident angle range, and the first reflectivity distribution has a greater reflectivity average value than the second reflectivity distribution.
